Exception when initiating GLGraphicsOffScreen

in Contributed Library Questions • 1 year ago

Hello.

I'm developing a game, and someone who tested it for me got this exception message when they tried to run the game:

javax.media.opengl.GLException
: Method "glRenderbufferStorageMultisam pleEXT" not available
at com.sun.opengl.impl.GLImpl.glR enderbufferStorageMultisampleE XT(GLImpl.java:17684)

at processing.core.PApplet.handle Draw(Unknown Source)
at processing.core.PApplet.run(Un known Source)
at java.lang.Thread.run(Unknown Source)

Line 163 in setup is:

offscreen = new GLGraphicsOffScreen(this, width, height, true, 4);

Any idea what this could be? Old gfx card drivers?

I'm using Processing 1.5.1 and GLGraphics 1.0.0

Old gfx card drivers?

Yes, that could be a possible reason. If after updating to the latest drivers you still get the error, that probably means that your video card doesn't support multisampled offscreen buffers. It that's the case, then try creating the offscreen object without the "true, 4" arguments.
